FUBBING AND FASTENING DEVICE.

Application filed March 28, 1922. Serial No. 547,414.

To all whom it may concern:

Be it known that I, Oran T. Cnown, re siding at Hayward, in the county of Alameda and State of California, have invented a new and useful F urring and Fas toning Device, of which the following is a specification.

This invention relates to devices for the furring of walls, and in particular to such a device in the form of a staple adapted to use with wire lathing, the combination forming the anchoring or foundation means to receive and support a plaster or cement coating for walls or the like.

The present common method of anchoring plaster to the exterior walls, of bungalows and buildings, is by laying wire mesh lathing over vertically positioned wooden furring strips, spaced about eight inches apart and nailed over building paper to the sheathing of the building. Plaster is then spread over the wall surface, and the wooden furring strips bedded in the wet plaster soon. absorb moisture and swell. As the plaster dries, the strips shrink more or less, thus unequal stresses are set up in the wall, re' sulting, upon close examination in fine hairlike cracks throughout the wall. These cracks tend to become longer and wider as the annual seasonal changes take place, and eventually patches of plaster drop off.

The main object of my invention is to overcome the above initial fine cracks, and thus extend the life of the wall to a very marked. degree and present a uniform and continuous surface. Other important ob jects of the furring device are, the quick application of it to the sheathng and build ing paper, and its effective holding power, its uniform outstanding distance from the sheathing surface, and the ease of application of the wire lathing over and to the hear-- ing surface of the staples, and their cheapness of production and simplicity.

I attain the above objects by the general formation of the staple and the manner of applying it to the wall as illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of the oreferred form of my staple. Fig. 2 shows the staple in its normal position on a wall, supporting the building paper and the wire lathing; the. Wall, paper and lathing being shown in section. Fig. 3 is an elevation of a section of wall showing three stages of completion. Fig. at is a side elevation of a modified form of staple, and Fig. 5 a per-- spective view of ano modification of it.

Throughout the figures, 1 represents the prong or the staple, 2 its driving head, 3 the shouldered stop-surface and 4 the outstanding supporting or bearing surface of the. device. The staple is preferably made of steel wire, formed with a wide mouth, the prongs being pointed and sloping inwardly a little for efficient driving. The drivinghead may be formed with a sharp curvature for hammer-surface and its under-portion for available straight-line stop-contact. The outstanding portion 4L may join the hammer head with a blunt curvature to eliminate corners and thus prevent the wire lathing from catching. The out-standing portion of the staple may be equal in depth to the length of the prongs as shown in Fig. 2. In this figure and also in F i 3, 5 represents the building sheathing, 6 the building paper, .7 the wire lathing and 8 an ordinary staple holding the latter on the supporting surface 4.

In Fig. 3 the building paper 6 is shown positioned on the wall and held thereon by the shoulder 3 of the staple; also a section of wire lathing is shown supported on the bear ing surface 4 ofthe staple, and 9 represents the plaster or cement, the finished wall bonded and held firm and stable by the wire lathing and staple reinforcing elements.

The modification of the staple of Fig. 4; shows but one prong, and in Fig. 5 the prongs are formed at right angles to the plane of the furring portion. In some cases I may prefer to use the latter forms in corners or other difiicult places.

In operation, the first step is to lay the building paper on the wall. This is accom plished by unrolling and laying the pape. thereon horizontally, starting at the bottom. The next strip is then laid partially overlapping the previous one, and so on to the top. The overlapping is for the purpose of shedding the moisture and water away from the. wood sheathing. The paper is secured to the sheathing by my staples, which are preferably positioned vertically and in staggered relation on the wall and driven therein until shoulder 3 contacts the paper.

The papered wall may now receive the wire lathing if available, or if not, at any time later.

The wire lathing is laid from the topdown, being unrolled upon the surface of the include staples, positioned and stretched doWn- Wards, and secured thereon by looping an ordinary staple over the juncture of my furring staple and lathing, and driving the same to position, thus completing the reinforcement foundation for the reception of the first coat of plaster. The plaster may then be spread on, the furring staples insuring a uniform even thickness of plaster, Well anchored to the wall surface and thus the stresses throughout the plaster mass equalize uniformly, resulting in a compact homogenous and continuous exterior wall.

Having described and illustrated my'invention in its preferred form, it is to be understood that I do not wish to be limited to the precise construction shown, but Wish to all modifications of it that come Within the spirit and scope of the claims,

What I claim as new and desire to secure by Letters Patent of the United States, is the following 2-- 1. In combination, a Wall sheathing, a

mamas double-humped staple of wide span adapted to be driven in said sheathing to thefirst hump, and Wire lathing adapted to be separately received and supported on the second hump of said staple, forming in conjunction therewith outstanding reinforcement for stucco Wall composition, the latter adapted to be spread on the sheathing surface and between and around the meshes of said rein forcement.

2.111 combination, a Wall sheathing,

building paper, a double-humped staple of around the meshes of said reinforcement.
